Cold Liquid-Applied Membrane

This is a broad range of products with a diversity that is not fully reflected in current standards. The products are delivered in fluid state and they cure by various mechanisms after application to form a continuous membrane. Material types include one-component—moisture curing, one-component with ac­celerator, and two-component. They are applied with trowels, brushes, rollers, and spray. The base chem­istry includes polymers, polymers modified with bitumen, and bitumen modified with a polymer. The materials may be reinforced with a fabric. This broad category of products is subject to the following ASTM standard and International Code Council (ICC) Evaluation Services (ES) Acceptance Criteria.
